A Catfish named for a Batman

A new species of South American catfish has been named Otocinclus batmani.
The 4-cm fish, from rivers in Columbia and Peru, has a tail marking resembling a black "bat" symbol. Ichthyologist Pablo Lehmann wrote, "The name batmani, alludes to Bob Kane's hero Batman of the comic adventures, which had a bat shape for his symbol, referring to the single W- or bat-shaped vertical spot on the caudal fin."
